The atomisp alone produces a way more warnings with smatch than all other media drivers. That prevents me to identify what's wrong on other drivers.
Cleanup the no-brain ones, in order to reduce the list to something that would be easier to handle. Still, after this series, we have several smatch warnings, and some seem to indicate real issues: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='/devel/smatch/smatch -p=kernel' M=drivers/staging/media drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/queue/src/queue.c:127 ia_css_queue_enqueue() internal error: sval_binop_signed: MOD by zero drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/queue/src/queue.c:185 ia_css_queue_dequeue() internal error: sval_binop_signed: MOD by zero drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:421 gmin_v1p2_ctrl() error: we previously assumed 'gs' could be null (see line 419) drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:455 gmin_v1p8_ctrl() error: we previously assumed 'gs' could be null (see line 453) drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:491 gmin_v2p8_ctrl() error: we previously assumed 'gs' could be null (see line 489) drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:667 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u32max > u32max)' drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/vf/vf_1.0/ia_css_vf.host.c:133 ia_css_vf_configure() warn: variable dereferenced before check 'binary' (see line 129) drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/output/output_1.0/ia_css_output.host.c:64 ia_css_output_config() warn: variable dereferenced before check 'from->info' (see line 63) drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c:1445 sh_css_update_host2sp_offline_frame() error: uninitialized symbol 'HIVE_ADDR_host_sp_com'. drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c:1476 sh_css_update_host2sp_mipi_frame() error: uninitialized symbol 'HIVE_ADDR_host_sp_com'. drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c:1503 sh_css_update_host2sp_mipi_metadata() error: uninitialized symbol 'HIVE_ADDR_host_sp_com'. drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c:1523 sh_css_update_host2sp_num_mipi_frames() error: uninitialized symbol 'HIVE_ADDR_host_sp_com'. drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c:1542 sh_css_update_host2sp_cont_num_raw_frames() error: uninitialized symbol 'HIVE_ADDR_host_sp_com'. drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/debug/src/ia_css_debug.c:3017 ia_css_debug_pipe_graph_dump_sp_raw_copy() warn: argument 4 to %08lx specifier is cast from pointer drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/mmu_private.h:24:26: warning: function 'mmu_reg_store' with external linkage has definition drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/mmu_private.h:35:30: warning: function 'mmu_reg_load' with external linkage has definition drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/eed1_8/ia_css_eed1_8.host.c:164 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_y[0][base + j]' drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/eed1_8/ia_css_eed1_8.host.c:168 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_a[0][base + j]' drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/input_system.c:907 input_system_configure_channel() error: buffer overflow 'config.input_switch_cfg.hsync_data_reg' 8 <= 8 drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_params.c:3808 sh_css_param_update_isp_params() error: uninitialized symbol 'stage'. drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_params.c:4155 sh_css_params_write_to_ddr_internal() warn: '((-(1 << ((14 -
